To all whom it may concern:

- Be it known that I, WILLIAM J. BREWER, a subject of the King of England, and a resident of Trenton, in "the county of Mercer and State of New Jersey, United States of America, have invented an 11..provement in Antifriction Wheel-Bearings, of which-the following is a specification.

My ihve'ntionis an'improvcment in the class of wheels an-l pulleys which are provided with antifri'ction bearings, and the features of novelty] are r as hereinafter described, and illu'stratd'in the accompanying drawings in which Figure 1 is a central/transverse section of a wheel or pulley provided withmy improvement. Fig. 2 is a section. taken at ri ht angle to thesection indicated in Fig. 1. ig; 3 is a face view of the inner side of one of the plates constituting an attachment of the wheel proper and embodying one of the chieffeatures of my invention. 4

1 indicates the hollow body of the small wheel, the same having a flat periphery and it being cast or otherwise formedintegrah The body 1 is provided with a central opening in each side and such opening is normally closed by a plate 3 whose construction and arrangcmentwill be hereinafter described.

4 indicates an axle which is concentric with the periphery 2 of the wheel and asses througho enin s provided in the side p ates 3 Around t e axle 4 are arranged antifriction. rollers or wheels 5, of which there are in this instance four, as indicated in Fig. 2; but three may be successfully employed. These rollers work in contact with the a'xle4, and in fact constitute the sole bearing for the same. a The peripheral or bod portions'of the rollers 5 are of considerably ess width than the transverse width ofthe chamber of the wheel, and the rollers are provided with T bosses 5 which work in frictional contact with the sides of the wheel proper.

6 also'passes through each of the wheels 5 An axle and also thrpugh openings provided in the body of the wheel 1 and likewise through coincident openings of the plates 3, sprlng pins 7 being inserted through openings in the ends of the axles for holding them in place.

Thus there is in each side of the body of the wheel 1 a series of concentric openings adapted to serve as bearings for the axles of the rollers 5, and the plates 3, which normally close the large central openings in the side's of the wheel, are also provided witha series 'which it is desired to remove.

n'ection it will be understood that the wheel of concentric 0 enings coineidentavith those in the wheel. has theside .pla tes Eserve as an additional bearing and support for eachof the axles 6.

It 'will be noted that the side openings in the body of the wheel which are closed by the plates 3 as shown in Fig.,1 are of'sli htly greater diameter than the diameter 0% the antifriction rollers 5. By .this meansit is provided that any of the rollers 5 may be removed from the body 1. through either of the larger openings of the latter, it being only necessary to. withdraw one of the pins 7 and slide the axle out of the particular roller Inthis conproper and axle 4 and sides 3 are first separated from each other.

The openings in the side plates 3 throu' h ameter'that'the axle does not come in contact I with the plates, the sole bearing for the axle .being,as before indicated, provided by the It will be seen that the.

concentric wheels 5. plates 3 .have an interior circular projection which isiada ted to fit neatly in the side openings of t e body 1 of the wheels or pulleys so that the side plates are heldfirmly in place as regards radial movement, or movement toward or from the periphery of the .Wheels.

which the axle 4 passes are made of such Each of the plates 3 is rovided' with an annular elastic packing 8', t e same being inserted and held in annular slots or recesses provided in. the edges of the lates which surround the axle, these '6l8iSt1CWilSh8IS8 work'in contact with the axle and serve as means to hold within the chamber of the wheel a lubricating agent, such as for example, graphite:

By means of its flat eriphery 2 the wheel lniay be used as sficii for small trucks or lar e vehicles.

W 'hat I claim is:

' 1. The im rovementcom body havin large central si e openings, and a series of t rec or more smaller openings arranged concentrically around the larger ones, antlfriction rollers and axles therefor whose bearings are in said smaller openings, and

side plates applied to, and closing, the larger openings of the body and havin a series of openings which coincide with t ose of the of the rollers and d evices applied to said axles rising a hollow v 1% eeneoe for holding them in place together with the I rollers; means for securing the axles together side plates, substantially as described. 7 with the side plates, the rollers being of less 2. The improvement described, comprisdiameter than the large central openings of ing a hollow body 1 havin large central side the body whereby they are adapted to be r'e- 15 openings, a series of anti riction rollers armoved therefrom, as and for the purpose ranged concentrically, and axles therefor as specified. described side plates which close the said .WILLIAM .side opcnmgs and are provided with a series I N B I of smaller openings coinciding with those of Witnesses: the body and adapted to receive, and-serve S.- D.
